facebook double-take
Person A starts yelling because they think Person B did something crazy. Person B looks like they’re about to cry. Then Person A says they saw it on Facebook and laughs like a maniac.
'You got a divorce?!' 'What? I didn’t say anything!' 'I saw your Facebook post, you lunatic!'
'You got a new job?!' 'What? I didn’t tell you!' 'I saw your post on Facebook, you nut!'
'You got a new haircut?!' 'What? I didn’t say anything!' 'I saw your Facebook, you crazy person!'
